High-dose precision radionuclide therapy (PRnT) by direct interstitial injection: optimizing therapeutic ratios for safe and effective delivery of high-dose radionuclide therapy in treating solid tumors

On November 3, 2023, the Georgian Health Physics Association welcomed Darrell Fisher, a seasoned nuclear medicine physicist representing Versant Medical Physics & Radiation Safety, to share his groundbreaking work in precision radionuclide therapy.   Fisher received his Ph.D. in nuclear engineering sciences from the University of Florida and carried a rich legacy of a 35-year tenure as a senior scientist and the lead of the Isotope Sciences Program at Pacific Northwest National Laboratory. His career also showcases his role as a science advisor to the U.S. Customs and Border Protection Commissioner between 2003 and 2005. Notably, Dr. Fisher has been a pivotal figure in leadership of the Health Physics Society, serving on its board of directors, as treasurer, and later as president of the society.

Analyzing dose parameters of radiation therapy treatment planning and estimation of their influence on secondary cancer risks

The Georgian Health Physics Association (GHPA) hosted an online technical meeting on October 6, 2023, featuring Maia Topeshashvili, MS, Chief Medical Physicist from the Radiation Oncology Department at Todua Clinic.

The meeting focused on the vital topic of estimating secondary cancer risk following breast cancer radiotherapy, employing organ equivalent dose (OED) concepts. Maia Topeshashvili's presentation provided crucial insights into this subject, with detailed findings from a study involving multiple breast cancer patients.

For comprehensive details on the study's results and implications, please refer to the abstract and the full presentation YouTube recording below.

Basic aspects of proton beam therapy

The monthly meeting of the Georgian Health Physics Association (GHPA) took place on September 29, 2023. At the commencement of this gathering, GHPA members were addressed by Victoria Brown, Chair of the HPS Society Support Committee. During her speech, Victoria shed light on the pivotal shift from the HPS board of directors' prior responsibility for chapter relations to the new oversight provided by members of the HPS Society Support Committee. She also spoke about the Joint IRPA-HPS nmeeting that will take place in Summer 2024. Her introductory remarks were followed by a technical presentation delivered by Beka Bochorishvili, a renowned Medical Physicist from Todua Clinic (Tbilisi, Georgia).

In January 2015, the HPS International Collaboration Committee (ICC) held the phone conference during which ICC members discussed the upcoming HPS 60th annual meeting activities, including plans for the ICC special session. It was particularly challenging to compile a list of international speakers. I immediately saw an opportunity for Dr. Chelidze, president-elect of the Georgian Health Physics Association (GHPA), to speak about current issues with radiation safety in Georgia.
